Subject: [PATCH v16 22/42] dept: apply timeout consideration to hashed-waitqueue wait
Date: Mon, 19 May 2025 18:18:06 +0900 [thread overview]
Message-ID: <20250519091826.19752-23-byungchul@sk.com> (raw)
In-Reply-To: <20250519091826.19752-1-byungchul@sk.com>
Now that CONFIG_DEPT_AGGRESSIVE_TIMEOUT_WAIT was introduced, apply the
consideration to hashed-waitqueue wait, assuming an input 'ret' in
___wait_var_event() macro is used as a timeout value.
